Hi all just wondering what the normal oil pressure range is cold/hot and idle/cruise on my style engine... Mine shows about 70-75 in cruise and 45 idle and hot.

Re: Normal Oil Pressure Range

Put a mechanical gauge on it and see what you get. That seems a bit on the high side for an old engine.\

Here is from the manual.

min. 2.1 kp/cm3 (30 psi),
nom 4.2–4.5 kp/cm2 (60–65 psi),
max 5.6 kp/cm2 (80 psi)
